JOHN L. LAIRDIESON, OF LOW'ELL, MASSACHUSETTS.

HEDDLE FRAME.

PECIFICATION forming part of Letters Patent No. 306,264, dated October 7, 1884.

Application filed October 9, 1883. (No model.)

T0 all whom it may concern,

Figure 1 is a front view of the lock-catcl1' separate; Fig. 2, a side view of the same; Fig. 3, a side view of one corner of a heddleframe, showing the catch applied thereto Fig. 4, a vertical section in a plane indicated by the line w m, Fig. 3; and Fig. 5, a crosssection in a plane indicated by the line y 7 Fig. 3.

Like letters designate corresponding parts in all of the figures.

The purpose of my invention is to provide a lJGddl6fI'tl116 having an improved fastening for removably holding the heddle bars or rods, the fastening not projecting at all from the surface of the frame, and the frame and fastening being so constructed that the fastening is self-retaining in the frame, and yet readily removed therefrom by hand.

The invention consists in the construction hereinafter described and claimed.

I make the catch A entirely of a single piece of elastic wire. The main part or body a is preferably formed straight, and has the catch part or pin Z) projecting substantially at right angles from the body. The tang or attaching part c is also straight,and is arranged preferably nearly parallel with the body a. The tang and body are connected by one or two coils, (Z, of the wire. These coils are not essential, but are desirable to increase the extent of the elastic portion of the catch, and to assist in holding the catch in proper position in the heddle-frame, as shown.

The construction of theframe to receive this catch is substantially as follows: A vertical hole, a, is bored in the end of the stile or side bar, 13,01" the heddle-frame to receive the tang c of the catch; also, a notch, f, is cut in the end of the stile to receive the coils d of the catch and sink that part within the outline surface of the stile, and to keep the catch from turning in the hole e out of proper position. The body a of the catch fits in a groove,

tisc of the stile. When the heddle bar or rod has been inserted in place, the catch-pin springs in through it and holds it securely in place, being a complete lock, since it cannot jar nor work out of place. Then, whenever the heddle bar or rod is to be removed, the catch-pin is simply lifted out far enough to relieve the same, and it is ready for removal. It will be seen that there is no part of the catch which projects at all beyond the bed dle-frame. The catch is so simple and is so easily made of such cheap material that the whole cost is trifling. The catch-pin I), being arranged substantially at right angles to the attaching-tang 0, holds the whole catch securely in the frame without any other means, and yet the catch can be removed instantly after lift-ing the pin 1) from the hole in the stile.

I claim as my invention 1. The combination, with the heddle-bar G and the heddle -frame having a groove, 9,

holes t and c, and cavity h, as described, of

a heddle-bar-locking catch, A, composed of a body, a, catch-pin b,- tang c, and coil (7, the said parts fitting respectively in the grooveg, holes 1 and e, andnotch h of the heddle-frame, whereby every part is adapted to lie within the surface of the said heddleframe, substan tially as and for the purpose herein specified.

2. The combination, with the heddle-frame having holes t and e, of a heddle-bar-locking catch, A, having a catch-pin, Z), and a tang, c, substantially at right angles to each other and fitting respectively in the holes i and e of the heddle-frame, similarly located in respect to each other, whereby the catch is securely held in the heddle-frame without additional means, substantially as specified.

In testimony whereof I have signed my name in presence of two witnesses.
